2in piston

[pat123]

I just posted something about a 4inch pvc pipe my uncle found. I may not use it because it might have fallen off of a truck going like 50mph.

in case i do use it I was wondering if my 2inch piston i made would constrict the flow on a 7ft 4inch pvc chamber.

If you are referring to a coaxial, a 2 inch piston should work nicely.

[iknowmy3tables]

why would you use a 2" piston on a coaxle with a 4" body,

can't you also increase the stroke length of the piston to increase flow

[pat123]

no i am talking about a over under

[spudgunnerwryyyyy]

Yes, build a piston valve in a 4" tee for max flow and less restriction.

i already made a piston in a 2inch tee i was wondering if it would work for the chamber size

[spudgunnerwryyyyy]

It would work with longer barrels. Is the porting 1.5" because that would work acceptably but not the best. It should work great. Amen to not having to build anything else or spend any more money.

[pat123]

yeah the porting is 1.5 the piston only cost me $7

[spudgunnerwryyyyy]

Awesome connect the valve to the chamber with threads so it is removable if you find out in the end that the setup doesn't work.

[iknowmy3tables]

why would it not work, you could always hackoff bits of the piston and bumper to increase flow but you don't need much space to dump an air chammber

Sorry typo it would work great.
